Description

Instrument with three cup anemometers attached to a plywood base. The base fits into a cover to make a carrying case. The anemometers consist of a metal pole with a vane made out of hemispherical cups affixed to an alias by rods. The center anemometer has four cups, while the two flanking outer ones have three cups.

Anemometers measure the speed and the direction of the wind, and are common instruments in meteorological studies. This instrument was made by a member of the MIT Department of Meteorology using three Robinson-type cup anemometers. Two were manufactured by Julien P. Friez and Sons, and one by Crouse-Hinds. Julien P. Friez and Sons was a manufacturer of weather instruments founded in 1876 in Baltimore, Maryland. Crouse-Hinds was established in 1897 in Syracuse, New York, and specialized in traffic controllers.
